Stuck in the middle: Impacts of grade configuration in public schools

We examine the implications of separating students of different grade levels across schools for the purposes of educational production. Specifically, we find that moving students from elementary to middle school in 6th or 7th grade causes significant drops in academic achievement. These effects are large (about 0.15 standard deviations), present for both math and English, and persist through grade 8, the last year for which we have achievement data. The effects are similar for boys and girls, but stronger for students with low levels of initial achievement. We instrument for middle school attendance using the grade range of the school students attended in grade 3, and employ specifications that control for student fixed effects. This leaves only one potential source of bias–correlation between grade range of a student's grade 3 school and unobservable characteristics that cause decreases in achievement precisely when students are due to switch schools–which we view as highly unlikely. We find little evidence that placing public school students into middle schools during adolescence is cost-effective.     

Royal finance under King Henry III, 1216–72: the wardrobe evidence1

Existing studies have shown how the royal wardrobe, the king's personal administrative office, regularly handled between a quarter and a half of the Crown's annual cash income. Despite this, the financial contribution of the wardrobe to royal finance under Henry III is not fully understood. For a reign in which debates about royal fiscal strategies are so notable a feature, this represents a significant gap. This article will supplement existing studies of wardrobe finance under Henry III by collectively analysing all 15 of the king's wardrobe accounts that are enrolled on the exchequer pipe rolls. The article makes two important findings. Firstly, the wardrobe was financially strong when the period of baronial reform began in 1258. Secondly, the wardrobe's financial strength was the result of a new, and deliberate, approach to acquiring revenue beyond the treasury that targeted sources of income that could generate cash quickly. During Henry's final years, this included greater reliance on credit. These findings suggest Henry III was not incapable of making adroit financial decisions. They also reveal that the foundations for the financial system developed by the three Edwards, which was more reliant on credit and sources of ready cash, were laid under Henry III.     

Retail Trading and IPO Returns in the Aftermarket

Using trade size from the Trade and Quote (TAQ) data set as a proxy for individual versus institutional trading, this paper finds that the effects of trading of these two types of investors on initial public offering (IPO) returns on the first trading day depend on the hotness of the IPO. My regression results reveal that IPOs’ open-to-close returns are positively related to small trade participation, small trade purchases, and small trade order imbalance in the hot IPO sample, but not in the cold and neutral IPO samples. In addition, the aftermarket prices of cold and neutral IPOs are primarily driven by the trading of institutional investors, who are less likely to be driven by sentiment.     

Effect of Money Supply on Real Output and Price in China

Over the past 30 years, China has achieved remarkable long-term economic growth. Using quarterly data, we study the effects of money supply on real output and inflation in China between 1993 and 2008. To this end, we use money supply shocks afler filtering out the expected component of the money supply. Our findings provide evidence supporting the asymmetric effect of positive and negative money supply shocks on real output and inflation in China. That is, real GDP growth in China responds to negative money supply shocks but not positive money supply shocks. In addition, inflation responds to positive money supply shocks but not negative money supply shocks. We conclude that the People＇s Bank of China＇ s policy of steady monetary growth appears to be appropriate. Our study offers important policy implications for China.     

Chinese children’s attitudes towards television advertising: truthfulness and liking

This benchmarking study examines Chinese children.s perceived truthfulness of and liking for television advertising in three Chinese cities with different developmental levels of advertising. An in-person survey of 1758 children (ages 6 to 14) was conducted between December 2001 and March 2002 using a structured questionnaire. Results indicate that a majority of children perceive half of the television commercials to be true, although this varies by grade and geography. Children in Beijing perceived television commercials to be more trustworthy than did children in Nanjing and Chengdu. The percentage of children who perceive all commercials to be true declines consistently with grade in all three cities. There is a high proportion of first graders who perceive all commercials to be untrue. The basis for judgement varies predominantly by grade. Children in higher grades depend more on brand and user experience while children in lower grades rely mainly on authority (i.e. parents or teachers). A high proportion of first graders hold both a strong liking and disliking for commercials. These strong feelings towards advertising decreased with grade, being replaced by a marked increase in neutral or indifferent feelings. Gender and level of television viewing do not show a consistent impact on perceived truthfulness and liking for commercials. Perceived truthfulness of television advertising is related positively with liking for commercials.

Green marketing and its impact on supply chain management in industrial markets

Green marketing and green supply chain have been drawing the attention of both academics and practitioners in the recent decade. However, no holistic framework has been developed on how to build green industrial brands and industrial corporate brands. Whether or not sustainable/green supply chains can be integrated with green industrial marketing in building greener organizations and industrial brands is still unclear. In addition, little is known on the factors on green new industrial product development or how green new industrial products are adopted by organizations. Furthermore, we know little of whether and how green supply chain enables green new industrial product development. This special issue aims at reflecting the most recent advances on green industrial marketing, green/sustainable supply chains and their interplay in green industrial branding, and to explore future research directions. The guest editors hope that the solicited papers can provide insights on the impacts of sustainable or green supply chains on marketing theory in industrial and business-to-business markets.     

Frequency of observation and the estimation of integrated volatility in deep and liquid financial markets

Using two newly available ultrahigh-frequency datasets, we investigate empirically how frequently one can sample certain foreign exchange and U.S. Treasury security returns without contaminating estimates of their integrated volatility with market microstructure noise. Using the standard realized volatility estimator, we find that one can sample dollar/euro returns as frequently as once every 15 to 20 s without contaminating estimates of integrated volatility; 10-year Treasury note returns may be sampled as frequently as once every 2 to 3 min on days without U.S. macroeconomic announcements, and as frequently as once every 40 s on announcement days. Using a simple realized kernel estimator, this sampling frequency can be increased to once every 2 to 5 s for dollar/euro returns and to about once every 30 to 40 s for T-note returns. These sampling frequencies, especially in the case of dollar/euro returns, are much higher than those that are generally recommended in the empirical literature on realized volatility in equity markets. The higher sampling frequencies for dollar/euro and T-note returns likely reflect the superior depth and liquidity of these markets.     

Forecasting volatility: Roles of sampling frequency and forecasting horizon

This study empirically tests how and to what extent the choice of the sampling frequency, the realized volatility (RV) measure, the forecasting horizon and the time‐series model affect the quality of volatility forecasting. Using highly synchronous executable quotes retrieved from an electronic trading platform, the study avoids the influence of various market microstructure factors in measuring RV with high‐frequency intraday data and in inferring implied volatility (IV) from option prices. The study shows that excluding non‐trading‐time volatility produces significant downward bias of RV by as much as 36%. Quality of prediction is significantly affected by the forecasting horizon and RV model, but is largely immune from the choice of sampling frequency. Consistent with prior research, IV outperforms time‐series forecasts; however, the information content of historical volatility critically depends on the choice of RV measure. © 2010 Wiley Periodicals, Inc.
